As OSGuy said, Romo?? Also, to a lesser extent, Big Ben. That guy walked onto an all-star team. He has an established receiver corps, historic defense, and outstanding running game. You could argue Ben both ways, though.
Your points about Colt's deep ball are hard to argue. He does still lob the long ones. I distinctly remember him throwing with plenty of zip early last year, when he was thrown into the fire. The only thing I can say to argue your deep ball complaints is "wait and see". There have been several 'noodlers' that have gone on to upgrade their deep ball. There have also been many who couldn't.
Since we're running a WCO, Colt also has the option of working around this weakness in his game. The offense is heavily dependent on timing (as I'm sure you know), so if he can excel at this and other key areas of the offense, he could stick. If it were any other offense, you'd probably be right that he's destined to be a backup.
Your other points about his performances against the Jets, Ravens, and Steelers are kind of ridiculous, though. Honestly, we got our butts handed to us in every aspect of those games (except the Jets game) and you want to focus on McCoy?
